ROLLS FOR ROLLING BARBED RODS.

SPECIFICATION forming part of Letters Patent No. 333,888, dated January 5, 1886.

Application filed August 28, 1885. Serial No. 175,585. (No model.)

To all whom it may concern Be it known that I, WILLIAM H. PERRY, a citizen of the United States, residing at Sharon, in the county of Mercer and State of Pennsylvania, have invented certain new and useful Improvements in Rolls for Forming Grooved and Barbed Bars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to the construction of rolls for the manufacture of that class of grooved and barbed rods and bars constituting the subject of an application for Letters Patent filed by me the 19th day ofAugust, 1885, Serial No. 174,815.

The object of my invention is, chiefly, to avoid the difficulty of making suitable rolls in solid chilled metal, in which, for the purpose of adapting the rolls to the formation of the grooves and barbs, the ridges and indentations by which the grooves and barbs are produced would have to be cut, thus involving very laborious and expensive operations.

My invention consists in constructing the rolls in peculiarly-shaped cylindrical sections of dimensions, number, and outline corresponding to or in keeping with the specific shape to be rolled. The sections by which the bar or rod is rolled and suitably grooved and barbed are secured in place and between the cylindrical sections constituting the body of the roll by bolts passing through the rolls from end to end, and are removable, so that the shapes of the barbing and grooving sections may be varied, sections of one shape being replaced by others, according to the kind of work to be performed.

Referring to the accompanying drawings, Figure 1 is a front elevation of a set of rolls embodying my invention, and Figs. 2, 3, 4 side views of the differentsections of which each roll is built.

A designates the rolls, mounted in suitable housings, B, and keyed to the shafts O in any suitable manner. Each roll comprises the two principal sections D D, of plain cylindrical outline, but rounded or beveled, if necessary, on their inner angles, a, a. Between these sections are arranged the disks or barfornling sections,of a size, shape, and number in keeping with the particular kind of rolling and shaping which they are to perform.

For illustration, I have shown the rolls as adapted for rolling cylindrical bars or rods having four grooves, with barbs or projections located in the grooves. E designates a bar or rod of such form. For producing such a bar or rod,I employ the central disk or section,G, having its periphery segmentally grooved or channeled, and the two disks H H, having their peripheries rounded or beveled and indented, as shown at g 9. Now, when the two rolls are in position their middle portions will include a cylindrical opening, K, of the diameter of the finished rod or bar, the edges of the disks H II projecting into said opening and beyond its walls. Then the bar or rod is passed through the rolls, it will be given its final reduction, and at the same time the grooves and barbs will be produced.

The sectional roll is adapted for rolling any other desired shapeas, for instance, oval, diamond shape, &c.suitably-shaped rolling and grooving disks being substituted for those shown in the drawings.

The disks H H are to be made of steel, and are of the character of saw-plates. All the sections are secured together and held rigidly in position by means of the bolts kk, having upon their ends the nuts 70 70', by removing which the sections may be displaced and others substituted.

What I claim as my invention, and desire to secure by Letters Patent, is-

In rolls for forming grooved and barbed rods or bars, the combination, with the cylindrical sections forming the body of the roll, and with an intermediate section of smaller diameter, of disks or plates having their edges indented or notched, said disks or plates being located between the said cylindrical sections and the intermediate section, and being separable or detachable therefrom, substan-- tially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
